There’s beauty in simplicity, and this tomato sauce proves exactly that. A few ripe tomatoes, gentle cooking, and time reveal the pure, bright essence of summer in every spoonful.
This sauce lets the natural sweetness of tomatoes shine without distraction. Use it as a base for pasta, pizza, or any dish where clean, unadulterated tomato flavor is the star.
Ingredients for Plain Tomato Sauce
Eight ingredients to capture summer in a sauce that lets tomatoes truly shine.
| Ingredient | Amount | Notes |
|---|---|---|
| Ripe Tomatoes 🍅 | 6 whole | Medium-sized, cored and quartered |
| Extra-Virgin Olive Oil 🫒 | 3 tbsp | High quality, fruity notes |
| Garlic Cloves 🧄 | 4 cloves | Peeled and lightly crushed |
| Fresh Basil Leaves 🌿 | ¼ cup | Loosely packed, torn by hand |
| Sea Salt 🧂 | 1 ½ tsp | Fine grain, adjust to taste |
| Black Pepper 🌶️ | ½ tsp | Freshly ground preferred |
| Red Pepper Flakes 🌶️ | ¼ tsp | Optional for subtle heat |
| Onion 🧅 | ½ whole | Yellow or white, finely diced |
Tomatoes are the soul here. Farmers market or homegrown will give you the best flavor—look for ones that smell sweet at the stem. I prefer San Marzano for their low acidity and sweetness, but any ripe tomato works. The olive oil should be something you’d happily drizzle on bread (I like California Olive Ranch for a good everyday option).
No fresh basil? Dried basil at one-third the amount works in a pinch. Out of garlic? A pinch of garlic powder can substitute, but fresh is ideal. If you want a smoother sauce, peel the tomatoes first (blanch for 30 seconds in boiling water). The red pepper flakes can be skipped if you prefer a milder flavor.
This sauce keeps beautifully. Store in an airtight container in the fridge for up to 5 days or freeze for 3 months. Portion into ice cube trays for easy single-serving use later.

Step-by-Step Instructions for Plain Tomato Sauce
Here’s the method to transform fresh ingredients into a bright, flavorful base for pasta.
Step 1: Sauté the Aromatic Base
Heat the 3 tbsp Extra-Virgin Olive Oil in a large saucepan over medium heat until it shimmers. Add the finely diced 0.5 whole Onion and cook for 5-6 minutes, stirring occasionally, until it becomes translucent and just begins to soften.
Add the 4 cloves Garlic Cloves (lightly crushed) and 0.25 tsp Red Pepper Flakes to the pan. Stir constantly for 30-45 seconds until the garlic releases its fragrance but doesn’t brown. This builds the flavor foundation without bitterness.
Step 2: Incorporate and Break Down the Tomatoes
Add all 6 whole Ripe Tomatoes (cored and quartered) to the saucepan. Stir to coat them in the aromatic oil. Increase the heat to medium-high and cook uncovered for 10-12 minutes, stirring occasionally.
The tomatoes will begin to break down and release their juices. Use a wooden spoon to gently crush the tomatoes against the side of the pan, accelerating the process. Continue cooking until the mixture reduces slightly and the tomatoes have mostly collapsed into a chunky sauce.
Step 3: Season and Simmer to Perfection
Stir in the 1.5 tsp Sea Salt and 0.5 tsp Black Pepper. Reduce the heat to low and let the sauce simmer uncovered for 15-20 minutes, stirring occasionally. The sauce should thicken slightly but maintain a loose, pourable consistency.
Taste and adjust the seasoning if needed. The flavors should be bright and balanced, with the natural sweetness of the tomatoes shining through. If the sauce becomes too thick, add a splash of water to reach your desired consistency.
Step 4: Finish with Fresh Basil
Remove the sauce from heat and stir in the 0.25 cup Fresh Basil Leaves (torn by hand). The residual heat will wilt the basil slightly while preserving its fresh, aromatic qualities. Let the sauce sit for 5 minutes to allow the flavors to meld.
Discard the garlic cloves if they remained whole. The sauce is now ready to be tossed with pasta or used as a base for other dishes. For a smoother texture, you can pulse the sauce with an immersion blender, though I prefer leaving it rustic and chunky.
Pro Tips For Making Plain Tomato Sauce
- Simmer Low and Slow: Keep the heat at a gentle simmer—too high and the sauce will splatter and reduce too fast, leaving you with a bitter, thick paste instead of a smooth, bright sauce.
- Score the Tomatoes: Before blanching, cut a small “X” in the bottom of each tomato; it makes peeling them a breeze and saves you from wrestling with stubborn skins.
- Skip Pre-Chopped Garlic: Fresh garlic cloves smashed just before cooking release more aroma and flavor than the jarred stuff, which can taste harsh and one-dimensional in such a simple sauce.
- Add Basil Late: Tear in fresh basil leaves only in the last 2-3 minutes of cooking—adding it earlier turns it dull and muddy, and you lose that vibrant, fresh pop that makes the sauce sing.
Make-Ahead Tips for This Recipe
Prep Ahead
You can prep all ingredients 1 day ahead—dice the 0.5 whole Onion, crush the 4 cloves Garlic, and quarter the 6 whole Ripe Tomatoes. Store them in separate airtight containers in the fridge. This saves time on cooking day. 💡
Cook in Advance
This sauce actually improves with time. Make it 1-2 days before using and store in the fridge. The flavors meld and deepen, giving you a richer, more harmonious sauce for your pasta or pizza base.
Batch Cooking
Double or triple the recipe and freeze in quart-sized freezer bags. Lay them flat to save space. When ready to use, thaw overnight in the fridge or submerge in cold water for 30-40 minutes.
Freezing Tips
Portion into ice cube trays for small batches. Freeze until solid, then transfer to a freezer bag. This way, you can grab just what you need—perfect for quick weeknight meals. ❄️
Reheating
Gently reheat in a saucepan over low-medium heat for 5-7 minutes, stirring occasionally. If frozen, thaw first in the fridge overnight. Add a splash of water if it thickens too much during storage.
Storage Duration
Fridge storage lasts 5 days in an airtight container. For freezing, it stays fresh for 3 months. Always label your containers with the date to keep track of freshness.

Frequently Asked Questions
Can I use canned tomatoes instead of fresh?
Use 28 oz canned whole tomatoes (drained) for similar results. Crushed tomatoes work too but may yield a thicker sauce. Canned are often more consistent year-round.
Why do I need to crush the tomatoes by hand?
Hand-crushing releases juices while keeping texture irregular. It prevents the sauce from becoming too smooth and maintains a rustic, chunky consistency that clings perfectly to pasta.
How do I fix sauce that’s too watery?
Simmer uncovered for 5-10 extra minutes to reduce. For quick fixes, mash a few extra tomato pieces or add a pinch of salt to help draw out moisture.
